Our most frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the exhaust remains composed at steady speed, ideal for daily driving.
• Race version: the loudest in the range, built for the track and driving enthusiasts. It is not intended for quiet long-distance trips.
• Fitting: the system uses the original mounting points. An equipped repair shop typically fits it in one to two hours.
